摘　　要：以某光热制蒸汽先导实验项目DSG吸热器为研究对象,采用多目标点镜场聚焦策略,根据吸热器结构和工质流程,基于热力学及流体力学定律建立吸热器水动力模型,计算并分析吸热器受光面各处热负荷分布以及流动特性。同时建立吸热器有限元模型,通过ANSYS软件进行吸热器有限元模拟,对理论计算结果进行验证。结果表明,多目标点聚焦策略下,吸热器管屏能量及温度分布更合理,不同工况下吸热器饱和水流速、出口含汽率以及饱和水压头均在合理范围内。Taking DSG receiver of one solar EOR pilot project as research object,establishes hydrodynamic mathematical model,calculates and analyses heat load and hydrodynamic characteristics of receiver based on multi-target focus model.Meanwhile the finite element model of receiver is established,the FEA is carried out by ANSYS in order to verify the theoretical calculation results.The results show that the energy and temperature distribution of the receiver is more reasonable under the multi-target focusing strategy.The saturated water velocity,working fluid exit dryness and saturated water pressure ratio are all in reasonable range.
